My understanding (from reading the most =recent issue of Byte) is that the ZMODEM protocol itself _is_ public domain, =and its development was funded by a major modem maufacturer (I don't recall =which one offhand).

I don't understand your attitude. Have you written to the publishers of all commercial comm programs that use X, Y, and/or ZMODEM protocols complaining that they are making money from public domain code? The protocols are in PD and will always remain there. That means that Omen or Datastorm or you or I may write software that uses them, yes, even to make money. Ward has never received a nickel for the concept or the implementation of XMODEM. So what? That was his choice. Chuck Forsberg writes wonderful software and chooses to (a) shareware some and (b) sell other straight commercially. Who cares whether you like him or his attitude. If you use his software, buy it. Otherwise, don't use it and keep quiet.
